Remove trailing slashes from filesystem paths

Paths with trailing slashes do not work on windows, they cause errors such as `django.core.exceptions.SuspiciousFileOperation: The joined path (C:\Projects\netbox\netbox\static\clipboard-2.0.4.min.js) is located outside of the base path component (C:\Projects\netbox\netbox\static\)`.
